Franklin et. al. (2005) defined volcanogenic massive sulphide deposits as stratabound accumulations of sulphide minerals that precipitated at or near the sea floor. All VMS deposits occur in terrains dominated by volcanic rocks, although individual deposits may be hosted by volcanic or sedimentary rocks that form part of the overall volcanic complex (Franklin, 1996). VMS deposits primarily occur in subaqueous, rift related environments (i.e. oceanic, fore-arc, back-arc, continental margins, or continental) and hosted by bi-modal mafic-felsic successions, where the felsic volcanic rocks have specific geochemical characteristics.

The Property has previously been classified as a VMS deposit because of the apparent stratabound nature of the mineralized zone. However, the Property also has affinities to epithermal deposits which is common in VMS deposits and the reported conformable nature of the mineralized zone could be due to the development of preferred mineralization along zones of structural weakness. The most common deposit types in the area are porphyry deposits, polymetallic base metal veins and the subvolcanic Cu-Ag-Au (As-Sb) deposit type.
